1. A power management system comprising:
at least one processor configured to:
control a power generation facility comprising power generation devices including a first power generation device and a second power generation device configured to generate power independently from the first power generation device; and
adjust an amount of supply of supply power to a load device which consumes generated power output by the power generation facility and the supply power supplied from a power system,
wherein the at least one processor is configured to control the power generation facility by:
determining whether or not to execute a process of reducing an amount of power generated by the power generation facility such that reverse power does not flow to the power system;
setting a priority for adjusting an amount of power generated by the first power generation device and the second power generation device of the power generation facility on the basis of a degree of fluctuation in load power predicted in the load device; and
controlling the power generation facility by adjusting the amount of power produced by each of the power generation devices based on a descending order of the priority when the process of reducing the amount of power generated by the power generation facility is determined to be executed.
